Counterfeit Islamic State-themed LEGO sets are being produced and exported out of China, depicting scenes of beheadings and ISIS flags. Some of the sets were discovered on sale in Malaysia after a mother noticed terrorist figures inside her sons LEGO set.

Mahnun Mat Isa said her son bought a ‘Falcon Commandos’ set for less than $2 from a store north of Kuala Lumpur. She noticed the set contained terrorist figurines wielding chainsaws, bloody heads, dynamite and ISIS flags. The set depictured counter-terrorism police officers clashing against ISIS figures and was recommended for children six and over, according to Australian news outlet 9 News.

“I ask authorities to not freely allow the entry of toys that touch on religious sensitives in this country,” she told Malaysian news site Berita Harian. “I came to know about it when my son, who was playing with the toy, showed me the terrorist character holding a banner which displayed the worlds ‘Allah’ and ‘Muhammad.’”

The set had a serial number on the box that was traced back to a manufacturer in China. The mother said she reported the set to police officers.

LEGO spokesperson Camilla Pederson told news outlet RT that the company had nothing to do with the counterfeit sets.

“This product is not a LEGO product — nor are the bricks in the set LEGO bricks,” she said. “As a company dedicated to inspiring and developing children, we would naturally never make a product like this.”

LEGO has long had a problem with counterfeit products, particularly coming out of China. A January video from BBC News shows even the head of LEGO’s Chinese factory being unable to discern between fake figurines and real ones.

“National patent, design and trademark laws — not to mention the observance of such laws and associated regulations — differ quite substantially from country to country,” the company said in a statement on its website. “In a number of countries, laws against unfair competition do not even exist. Lately, the absence of regulations against counterfeiting, trademark infringements, etc., has confronted the owners of original rights with growing problems from copy producers.”

More than 400 billion LEGO pieces have been produced since the company’s founding in 1932. But Asia has historically contributed very little to the company’s market, providing little revenue over the years, according to Quartz. In an attempt to curb counterfeit production, LEGO opened a manufacturing facility in China and sued counterfeit brand LEPIN in court.

“We are committed to do whatever necessary to protect the LEGO brand and products against undue exploitation,” the company said in a statement about the lawsuit. “And to minimize the risk of consumers being misled via improper use of LEGO Group intellectual property assets.”
